Visiting the Emergency Room (ER) is never a pleasant experience, but for chronic illness patients, the stakes feel even higher. Questions swirl in your mind as you wonder how to prepare, whether you'll be taken seriously, or what to do after you're discharged. These concerns are valid—but the good news is, you’re not alone.

This guide is here to answer your most pressing questions about navigating an ER visit as someone with a chronic or invisible illness. We’ll cover everything from preparation to advocacy tips, all designed to give you a sense of control and relief in what can otherwise be a difficult situation.

Should I Go to the ER or Contact My Primary Care Team First?

The biggest question many chronic illness patients face is whether they’re overreacting by considering an ER visit. The answer is simple when things are urgent or life-threatening: always choose the ER. Conditions such as severe chest pain, difficulty breathing, sudden weakness, or heavy bleeding should never wait. These are genuine emergencies.

For less critical problems, your Chronius care team can help you assess your next steps. If you're unsure, reach out to a healthcare provider or nurse hotline first. Your care team is well-equipped to understand your unique condition and guide you accordingly.

Pro Tip: Keep a short, personalized list of symptoms and red flags that will always mean "go straight to the ER." Need help creating this list? Chronius can work with you to identify your specific warning signs.

Will the ER Know About My Care Plan or Diagnoses?

Unfortunately, the ER won’t automatically have access to your Chronius care plan or health history. That’s why preparation is essential.

To make your visit smoother:

  • Keep a printed or digital medical summary of your diagnoses, medications, allergies, and emergency protocols. You can request this from your Chronius provider.

  • Bring copies of any specialist letters or treatment notes that explain your condition in more detail.

  • Consider a "flare letter" from your Chronius care team. This document explains your illness and outlines tailored recommendations for ER care.

Without these tools, ER doctors may focus solely on immediate risks and overlook the nuances of your condition. Be ready to represent your own medical history.

Can My Doctor Communicate With the ER on My Behalf?

While your doctor may sometimes call the ER to share important information about your condition or medical history, their ability to do so depends on their availability. Additionally, the ER's response may vary based on how busy they are and the urgency of the situation. Relying on this alone isn’t always the best option. At Chronius, we’re here to help you prepare for the ER and ensure the best care:

  • Before the ER: Make sure you have a high-level overview of your medical records, including a list of diagnoses and medications. Chronius can provide this for you, or you can request it from your primary care doctor (PCP).

  • At the ER: Let the staff know who your PCP is and provide their contact information so the ER doctor can reach out if needed.

  • After the ER: Ensure the ER faxes your records to your PCP or access them through your patient portal. Schedule a visit with your PCP within 5 days to review the outcome and create a follow-up plan.

Navigating the ER can feel overwhelming, but preparation and communication can make all the difference. Through our flare care plans, Chronius is here to simplify the process and support you every step of the way each time you require an ER visit.

What Should I Tell ER Doctors so They Take Me Seriously?

One of the most common fears for chronic illness patients is not being believed, especially if you have an invisible illness. The key is to advocate for yourself calmly, clearly, and concisely.

Here are some tips:

  • Start Strong – Lead with Your Urgent Symptoms: Begin by saying, "I have [condition], but I’m here because [urgent symptom]. It’s getting worse and not responding to usual treatment." This helps frame the urgency right away.

  • Use Key Phrases to Keep Focus on Acute Needs: ER doctors prioritize immediate issues, so focus on changes from your baseline. For example: "This is different from my usual flares—I need help managing it now."

  • Avoid Overloading with Diagnoses: Share formal diagnoses upfront only if relevant, but avoid listing your entire medical history. Instead, try saying: "I usually manage my condition, but this is severe and unmanageable."

  • Avoid Minimizing Language: Skip phrases like "I think it’s just stress" and instead emphasize: "This feels different and needs evaluation."

Pro Tip: Stay assertive but polite, and remember that Chronius can help review your visit after the fact to ensure any gaps in care get addressed.

What Happens After the ER Visit? Do I Need to Contact my PCP?

Yes, connecting with your primary care team after an ER visit is essential. Here’s what Chronius can do post-discharge:

  • Review Discharge Information: What happened while you were there? Share documentation like discharge summaries, new prescriptions, and any tests ordered.

  • Adjust Care Plans: If the ER visit revealed new diagnoses or needs, we’ll help update your treatment plan to reflect those changes.

  • Coordinate Follow-Ups: Whether you’ve been referred to a specialist or need additional tests, we’ll arrange everything to ensure seamless care.

Take the time to recover emotionally as well as physically. ER trips can be draining, and Chronius is here to ease that burden, one step at a time.

Can Chronius Help Me Avoid Future ER Visits?

Avoiding future ER visits is often possible with advanced planning and intervention strategies. Here’s how Chronius plays a role:

  • Flare Planning: We work with you to create detailed contingency plans for managing potential symptoms before they escalate.

  • Early Interventions: Regular doctor and nurse visits can help identify potential health issues before they escalate, while faster diagnoses ensure timely treatment. Preventative screenings and proactive health monitoring are also key to catching concerns early and improving outcomes.

  • Symptom Tracking: Chronius helps monitor recurring health patterns, giving you the insights needed to make proactive adjustments.

What do I Pack in my ER "Go Bag"?

Emergencies are unpredictable, but you can set yourself up for success by packing a "go bag" just in case. Here’s what to include:

  • Copies of your medical summary, diagnoses, and medications

  • Letters or notes from your care team

  • A phone charger, snacks, and noise-canceling headphones

  • Emergency contact list (include both loved ones and medical professionals)

  • Comfort items like a blanket or stress ball

Preparation doesn’t just make your visit easier; it also helps ER staff deliver the care you need faster.
